Abstract

Using automated protein sequence analysis of BALB/c myeloma proteins, the genetic basis for antibody specificity and diversity is investigated. Studies on the N-terminal regions of the heavy chains from these immunoglobulins reveal that a large amount of diversity must exist in the VH regions. Examination of the heavy and light chain sequences from myeloma proteins with hapten-binding activities indicates that the heavy chain variable region sequence correlates closely with all the specificities of intact molecules. The light chain appears to be less restricted in some specificities, however. The relevance of these data to the proposed mechanisms of antibody diversity is discussed.
